# U.S. inflation rate in 1867: -6.92%

### Inflation in 1867 and Its Effect on Dollar Value

Purchasing power increased by 6.92% in 1867 compared to 1866. On average, you would have to spend 6.92% less money in 1867 than in 1866 for the same item. This is an example of deflation.

In other words, \$1 in 1866 is equivalent in purchasing power to about \$0.93 in 1867.

The 1866 inflation rate was -2.45%. The inflation rate in 1867 was -6.92%. The 1867 inflation rate is lower compared to the average inflation rate of 1.88% per year between 1867 and 2020.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1867 was 14.80. It was 15.90 in the previous year, 1866. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1867 CPI is less than 1866 CPI, negative inflation (also known as deflation) has occurred.

### Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1866 would be equivalent to £1.06 in 1867, an absolute change of £0.06 and a cumulative change of 6.32%.

Compare these numbers to the US's overall absolute change of \$-0.07 and total percent change of -6.92%.

### Inflation by Spending Category

CPI is the weighted combination of many categories of spending that are tracked by the government. This chart shows the average rate of inflation for select CPI categories between 1866 and 1867.

Compare these values to the overall average of -6.92% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 1866 → 1867
Food and beverages 0.00 0.00 1.00
Housing 0.00 0.00 1.00
Apparel 0.00 0.00 1.00
Transportation 0.00 0.00 1.00
Medical care 0.00 0.00 1.00
Recreation 0.00 0.00 1.00
Education and communication 0.00 0.00 1.00
Other goods and services 0.00 0.00 1.00

For all these visualizations, it's important to note that not all categories may have been tracked since 1866. This table and charts use the earliest available data for each category.

### How to Calculate Inflation Rate for \$1, 1866 to 1867

This inflation calculator uses the following inflation rate formula:

CPI in 1867CPI in 1866
×
1866 USD value
=
1867 USD value

Then plug in historical CPI values. The U.S. CPI was 15.9 in the year 1866 and 14.8 in 1867:

14.815.9
×
\$1
=
\$0.93

\$1 in 1866 has the same "purchasing power" or "buying power" as \$0.93 in 1867.

To get the total inflation rate for the 1 years between 1866 and 1867, we use the following formula:

CPI in 1867 - CPI in 1866CPI in 1866
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

14.8 - 15.915.9
×
100
=
-7%

### Data Source & Citation

Raw data for these calculations comes from the Bureau of Labor Statistics' (CPI), established in 1913. Inflation data from 1665 to 1912 is sourced from a historical study conducted by political science professor Robert Sahr at Oregon State University.
